Application filed July 3, 1918.

To allee/wm t may concern.'

Be it known that we, FRED L. MAonnNzrn and Grenen GoDDU citizens of the United States, residino` at everly, in the county of Essex, and lt'nchester, in the county of Middlesex, respectively, and State of Massachusetts, have invented certain Improvements in fork-Guides, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to guiding devices for machines comprising mechanism for operating on shoe stock and has special reference to devices for guiding a strip or strips of shoe stoel; into position for operation thereon by said operating mechanism.

It has heretofore been proposed to interpose between the welt and the upper and insole of a welt shoe a filling strip of compres` sible elastic, and impervious material, such as rubber, which will preclude the seeping of moisture between the welt and the upper the attachment of the welt to the upper and insole by metallic fastenings spaced from each other along the margin of the shoe,

Vmay be made substantially waterproof by the interposition of a strip of rubber or like material between the welt and the upper and insole so as to be compressed therebetween when the parts are secured together by the fastenings and thus preclude seeping of moisture between the welt and the upper and insole intermediate of the spaced fastenings or through the perforations of the welt and upper and insole in which the fastenings are inserted. The filling strip is preferably formed with a beaded edge which when the welt and filling strip are laid on the shoe overhangs the margin of the upper and insole adjacent thereto and lies in the angle. formed by the welt and upper.

An object of the invention is to facilitate the manufacture of shoes of the type above set forth by the provision of devices for effectively controlling a welt strip and a lilling strip and guiding them in superposed relation to the point of Operation on the Specification of Letters Patent.

strips. To this end, the guiding devices are formed to accommodate the bead of the fill ing strip and by said bead to control the `filling strip in its relation to the welt and operating means. The illustrated embodiment of the invention is particularly intended for use in guiding a welt and a beaded filling strip into position for attach ment to a shoe by metallic fastenings and is provided with a guiding passage which receives the welt and the filling strip in oontact with each other and which is notched in its 4bottoni wall to accommodate the bead on the filling strip and to present surfaces for guiding engagement with the beaded edge of the filling strip.

Although the use of the invention now particularly contemplated is in the attachment to an upper and an insole of a welt and a coinpressiblen and waterproof filling strip interposed between the welt and the upper and the insole, it is recognized that the invention as a whole and certain features thereof may have other applications. In one of such aspects, an important feature of the invention resides in the provision of means for guiding a plurality of strips pro-V viding a guiding surface arranged for guiding engagement with a side of one of said strips and a member arranged for engagement with the opposite side of said iirstmentioned strip and formed to present a guiding surface for engagement with an edge of another of said strips thus Veffectively controlling said strips and accurately positioning them relatively to each other.

In the illustrated construction, the guiding devices are associated with the guard plate of a fastening inserting machine, the guard plate being provided on one of its sides and rearwardly of the point of insertion of the fastenings with a guiding passage which receives the welt superposed on the illing strip. A second plate secured to the lower surface of the guard plate and hereinafter for convenience sometimes de-V nominated the guide plate is formed to present a guiding surface arranged for engagement with the edge of the welt adjacent to the point of insertion of the fastenings and carries a gage roll which operates toposition the shoe relatively to the fastening inserting` mechanism. Pivoted upon the guide Cri plate is a finger the end of which is inter posed between the end of said plate and the gage roll and is constructed and arranged to underlie a portion of the welt substantially at the point of fastening insertion and to present a guiding surface for engagement with the beaded edge of the filling strip. The pivotal mounting of the finger on the guide plate permits movement of the finger between the lower surface of the end of the plate and the upper surface of the gage roll, the finger being normally pressed against the lower surface of the welt by a spring tending normally to move the end of the finger upwardly toward the lower guiding surface of the guard plate which engages the upper side of the welt. As before indicated, the guiding passage of the guard plate is formed with a notch in its lower wall to receive the bead on the filling strip, and this notch is of greater extent than the bead to permit the bead to be positioned at varying distances from the inner edge of the welt to the end that filling strips ef different widths may be accommodated, and, in order that filling strips of different widths may be positively guided inte proper relation with the shoe, the aforementioned finger is mounted for endwise adjustment on the guide plate.

Other objects and features of the inventien will appear as the description proceets and will be pointed out in the appended claims.

Fig. l illustrates a block to which the filling strip guiding finger is pivoted and by which said finger is adj ustably mounted relatively to the guard plate, and

Fig. 5 is a view in detail of the finger which guides the beaded edge of the filling strip underlies a portion of the welt.

The fastening inserting machine to which the invention is applied by way of example may be of the type disclosed in the co-pending application of Fred L. Mackenzie, Serial No. 137,152, filed December '15, 1916, comprising the frame 2 which. carries a swinging head 4 upon which is mounted the fastening inserting instrumentalities comprising a driver (not shown) and an awl 6. Carried by the main frame 2 is a guard plate 8 which is formed to provide a lower guiding surface 10 (see Fig. 2) leading to and lying at each side of the point of insertion of the fasten ings. The shoe to which the welt A and filling strip B are attached comprises the insole C and upper D and is supported on a horn 11.

The guiding devices for the welt A and filling strip B comprise a bracket 12 adjustably joined to one side of the guard plate 8 by screw and slot connections 14 and formed at its outer end in alinement with the point of insertion of the fastenings with a guiding passage having an upper surface 16 for engagement with the upper side of the welt A, a surface 18 for engagement with the inner edges of both the welt A and the filling strip B, a surface 2O for engagement with the outer or projecting edge of the welt, and a lower wall 22 provided with a notch 24 to receive the bead E on the filling strip and presenting surfaces for guiding engagement with the bead of the filling strip to control the filling strip relatively to the welt and the fastening inserting mechanism and with the side of the strip from which the bead projects. rlhe notch further presents a surface 26 arranged for engagement with the outer edge of the filling strip in substantially parallel relation with the surface 2() which engages the outer edge of the welt. The shape and arrangement of the lower wall 22 with its notch 2d permits the bead of the filling strip to pass through the guiding passage without disturbing the proper guiding relation of the sides and opposite edge of the strip and their respective guiding surfaces. The surface 2O is presented by a part 28 adjustably connected to the bracket 12 by the screw and slot connection 29 whereby the guiding surface 20 is made adjustable relatively to the bracket 12 to adapt it to welts of varying widths. j A guide member 30 (see Fig. 2) extends laterally from the forward end of the bracket 12 and presents a guiding surface 31 alined with the guiding surface 1S and extending to a point adjacent to the point of fastening insertion. By reference to the drawing, it will be seen that the guiding passage in the bracket 12 is formed te receive and guide the welt A and filling strip B in Contact with each other and to arrange the welt A 'and filling strip B transversely in substantially straight lines and in substantially parallel planes. A welt guide of the general type of that thus far described and comprising a bracket formed with a guiding passage to receive a welt and having a part formed to present a guiding surface for the outer edge of the welt which is adjustable relatively to the guiding passage of the bracket is disclosed in the copending application of George Goddu, Serial No. 97,015, filed May 12, 1916, on which Patent No. 1,282,809 was granted Oct. es, 191e.

8. In a machine of the class described, means for attaching a plurality of strips of shoe stock of varying Widths to a shoe, and means for guiding said strips and presenting them to said attaching means in superposed relation comprising a member formed to present a guiding passage arranged rearwardly of the point of attachment of the strips to the shoe and constructed to receive and guide said strips anda member underlying one of said strips and acting to support said strip substantially at the point of attachment of the strips to the shoe and engaging the edge of another of said strips"to guide the last mentioned strip substantiallyv at the point of attachment of the strips to the shoe.

9. In a machine of the class described, a guide formed to present a guiding passage to receive and guide a plurality of strips of shoe stock of varying Widths and having a surface for engagement with an edge of the Wider of said strips and a second surface spaced from the first-mentioned surface for engagement With an edge of a narrower one of said strips to position said last-mentioned strip in proper relation tothe first-mentioned strip, said guide also comprising a member underlying a portion of the Wider strip and presenting a guiding surface in substantial alinement with the second-mentioned surface of the guiding passage for engagement with the edge of the narrower strip. v

10. In a machine of the class described, means for attaching a filling strip having a bead projecting from its side adjacent to one of its edges and a Welt to a shoe and means for guiding the filling strip and Welt to said attaching means with the Welt superposed on the filling strip comprising a member organized for guiding engagement therewith rearwardly of the point of attachment of the filling strip and Welt to the shoe and constructed to receive the bead of to locate the welt and filling strip accurately at the point of fastening insertion. Additional means `for guiding the welt and fill-- ing strip whichV will positively assure the accurate positioning of the welt and filling strip are provided, such means comprising a plate 32 adjustably connected to the guard plate 8 by bolts or the like (not shown) which pass through slots 34 insaid plate and formed to present a guiding surface 36 for engagement with the outer edge of the welt A ad'acent to the point of insertion of the fastenings. Adjustment of the plate 32 relatively to the guard plate 8 permits the guiding surface 36 of the plate 32 to be alined with the guiding surface 20 of the bracket 12 in the various adjustments of said guiding surface 20. The part 28 has its end turned laterally and extended through the passage of the bracket 12 toward the point of fastening insertion to a point adjacent to the rounded end 36 of the plate 32 so that the guiding surfaces 20 and 31 and the guiding surface 36 which acts as an extension of the guiding surface 20 operate positively to guide the welt and filling strip to the point of fastening insertion. Carried by the guide plate 32 is a finger- 38 having its forward end arranged to underlie a portion of the welt A and formed to present a guiding surface 39 for guiding engagement with the outer or beaded edge ofthe filling strip B. The end of the finger 38 underlies the welt A and engages the filling strip B substantially at the point of insertion of the fastenings and supports the welt A at that point. The finger 38 thus acts to maintain the welt A against the lower guiding surface l0 of the guard plate 8. To the end that welts of various thicknesses may be accommodated between the guiding surface 10 of the guard plate and the finger 38,V the finger is mounted for movement to and from the end of the plate 32 which engages the outer edge of the welt, as shown, by being pivoted at 40 to a block 42 which is dove-tailed slidably into the side of the guide plate 32 and is adjustably connected to said plate by the screw and slot connections 44 and normally held against the lower side of the welt A by a coiled spring 46 operating against a pin 48 seated in the finger 38. A finger piece 49 is formed on the finger 38 whereby the forward end of the finger may be lowered by the operator from the surface 10 of the guard plate 8 against the tension of the spring 46 to permit ready introduction of the welt A between the finger and the surface of the guard plate. The lower surface of the plate 32 is recessed to receive the shank portion 5() of the finger 38 thereby presenting depending portions 52 positioned at each side of the shank of the finger. i Said depending portions 52 (see Fig. 1 and broken lines F ig. 3) do not extend to the end of the plate 32 but sto-p short of the end of the guide plate sufficiently far to permit the greater portion of the T-shaped end of the finger 38 to lie in the recess formed in the plate forwardly of said depending portions. The depending portions 52 of the plate 32 extend downwardly far enough to confine the shank 50 ofthe finger 38 between them at the extreme downward limit of movement of the forward end of the finger. Such parts 52 guide the finger in its endwise adjustments and serve at all times to maintain the finger against dislocation laterally.

' The plate 32 has fitted in a groove on its lower side a slide 54 which has a pin 56 projecting downwardly therefrom and received within a cam slot 58 formed in a lever 6() pivoted on a pin 62 seated in said plate and passing through a slot 64 in the slide 54 to permit movement of the slide relatively to the fixed pin. Said slide 54 has adj ustably secured thereto at 65 a bracket 66 carrying a gage roll 68 arranged for engagement with the upper of the shoe adjacent to the edge of the insole to position the shoe relatively to the fastening inserting mechanism and the guiding devices for the welt A and filling strip B. The extent of adjustment of the gage roll 68 away fiom the fastening inserting mechanism may be regulated by the set screw 70 mounted in a bracket extending laterally from the plate 32.

j The arrangement of the bead on the filling strip relatively to the margin of the shoe should be the same regardless of variation in widths of the fillin strips, for which reason it is essential that t e guiding device for the edge of the filling strip have a constant relation to the gage roll 68 which positions the shoe. It will be evident from the foregoing description that in the present construction the finger 38 which guides the filling'strip and the gage roll 68 may be adjusted together relatively to the guard plate 8 and the fastening inserting mechanism by movement of the plate 32 relatively to the guard plate 8, such movement being permitted by the slots 34 in the plate 32. It is further apparent that the notch 24 of the guiding passage formed in the bracket 12 permits adjustment of the filling strip relatively to the welt, such adjustment being effected by'movement of the finger 38 endwise relatively to the plate 32 or, if it is desired to adjust simultaneously the gage roll 68 and the guiding surface 36 for the edge of the welt, the plate 32 may be moved relatively to the guard plate 8, thereby adjusting the filling strip B as well as the shoe relatively to the fastening inserting mechamsm.

the filling strip in a manner to permit adjustment of the filling strip transversely of thel welt and a member presenting a guiding surface for engagement with the edge of the welt adj acent to the point of attachment of the strip to the Shoe and a second guiding surface for engagement with the beaded edge of the filling strip and means for adjusting said second guiding surface to compensate for variations in width of the filling strip.
